Application of Biodiesel-Diesel Blend as the Continuous Phase in Drilling Fluid

Abstract

This dissertation explores the use of biodiesel from waste cooking oil as an alternative base fluid in oil-based drilling muds. Various biodiesel-diesel blends were tested for rheology, emulsion stability, and thermal performance. Biodiesel offers environmental benefits such as biodegradability and non-toxicity. The study concludes that biodiesel-rich blends are viable for drilling use and recommends further testing on other biodiesel sources, biodegradability, and glycerol reuse.
